The reason your puppy or a dog is reacting to your vacuum cleaner is because it’s something new in the room and it makes a loud sound and moves erratically! “Fight or flight! I can’t let myself outside, so ATTACK or HIDE.” Try this: Take your vacuum cleaner out of the closet and leave it in the living room. Don’t plug it in. Don’t turn it on. Just let your dog get used to it being there. Next, do some training and basic commands right next to the vacuum. You want to create a positive association
